Recent forecasts from the Japan Meteorological Agency indicate stable high-pressure conditions over Tokyo, with southerly flow and minimal cloud cover supporting a daytime maximum of 28°C on May 17. Official model consensus places the peak squarely in this range, consistent with May climatology where urban heat island effects often push readings 2–4°C above regional baselines. Trader consensus at near-certainty reflects these verified atmospheric patterns and the narrow uncertainty band in current guidance. A realistic challenge would require rapid development of an unexpected frontal boundary or heavier afternoon showers that suppress temperatures below the threshold.
